Hi Loopy,
I am so sorry for how you feel right now. I completely understand. My symptoms are/have been pretty severe (full toilet of blood and mucous 10/day), but when I was diagnosed with c-diff it was completely unbearable - the pain, the D, the dehydration, the anemia... it was hard to find the strength even to sit up in bed, let alone have a hopeful attitude.
I insisted on getting my stool checked for the next month because I heard that the spores are not killed by the antibiotics. Please keep an eye on that too. Oh, by the way, at the same time I had flaring UC, and C-diff, I also had Camphylobacto (sp?). Our flora is all off, so we are susceptible. After megadosing on probiotics for 3 weeks, my stool still showed ZERO bifidus in my stool.
Lots of people on this site recommend VSL#3. I haven't tried it yet, but I plan on it soon.
Be gentle with yourself and I hope you start feeling better soon.
